Description -
 
Forged Flat-Top Piston to Fit GX390 and UT2 GX340
Stock bore uses factory compression height and stock wrist pin diameter so it will drop in using a standard length rod. No cutting of piston.

New style pistons have valve reliefs for high-lift cams.

This piston will provide approximately 1-1.5 points increase in compression. It can be used with our .040 longer rod for even more increase.

Designed to use OEM Honda piston rings: 13010-Z5R-004.
Can also use aftermarket rings: RINGSET-88-046046104-B.

*Wrist pin and clips included, but rings are not included!
